Expedient Synthesis of Substituted Thieno[3,2-<i>b</i>]thiophenes and Selenopheno[3,2-<i>b</i>]selenophenes Through Cascade Cyclization of Alkynyl Diol Derivatives

Expedient Synthesis of Substituted Thieno[3,2-<i>b</i>]thiophenes and Selenopheno[3,2-<i>b</i>]selenophenes Through Cascade Cyclization of Alkynyl Diol Derivatives

Thieno[3,2-<i>b</i>]thiophenes are used as key components in optoelectronic materials, porous hydrogen-storage hosts, organic solar cells, and polymer semiconductors. A step-efficient synthetic protocol was proposed herein for obtaining multisubstituted thieno[3,2-<i>b</i>]th...
